2 Claims."

This invention relates to reed horns and pertains particularly to a dual tone reed horn adapted to be mounted on a bicycle handle bar or the like.

One object of the present invention is to provide a reed horn including dual reeds and dual horn sections in order to effect dual tones upon a single blast of air past said reeds. I

Another object of the present invention is 1; provide a reed horn including a single reed and dual horn sections, each horn section receiving the same tone from said reed but being adapted to alter said tone to thereby effect dual tones upon a single blast of air past said single reed.

Another object of the present invention is to provide novel horn reeds which are adapted for facilitated entrance into and self-retention in the reed passages of reed horns.

Still another object of the present invention is to provide a novel reed horn formed as a single die casting and having integral therewith one-half of the bracket required for mounting the horn on a bicycle handle bar or the like.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

Fig. 1 is an end View of the first embodiment of the invention but with bulb omitted to illustrate the disposition of the dual reeds in the neck portion.

Fig. 2 is a sectional view taken along the lines 2-2 in Fig. 1, but with the bulb added.

Fig. 3 is a sectional view taken along the lines 3--3 in Fig. 2 and illustrates features of construction of the integral mounting element.

Fig. 4 is an isometric view of a form of dual reed construction employed in the first embodiment.

Fig. 5 is a side elevational view of an independently formed mounting element adapted to associate with the integral mounting element.

Fig. 6 is an end view of the element seen in Fig. 5.

Fig. 7 is an end view of a second embodiment of the invention and shows the disposition of a single reed construction in the reed passage.

Fig. 8 is a sectional View taken along the lines 8-8 in Fig. 7, but with the integral mounting 2 element shown in full and the bulb or air blasting means indicated by dot and dash lines.

Fig. 9 is an isometric view of a form of single reed construction employed in the second embodiment.

Fig. 10 is another longitudinal sectional view similar to Fig. 2, but illustrating the horn constructed in accordance with a still further modification of the present invention.

With reference to the drawings in more detail, and particularly to Figs. 1 to 6, it will be seen that the first embodiment of the invention provides a horn I0 having first and second horn sections II and I2, respectively, and a neck section I3.

Said horn is of a one-piece construction and is preferably die cast. As best seen in Fig. 2 the said first horn section II is of greater length than the mentioned second horn section I2 and as a result said sections aredifierently pitched. However, the neck section I3 is common to the inlets to both the horn sections.

Disposed and retained in the neck section I3, in a manner to be described hereinafter; is a reed construction I4 having a low pitched reed I5 and a high pitched reed I6 formed therein. Said reed construction I4 as seen in Fig. 4, also, is preferably of a resilient metal and is formed with an upper portion H, in which the low pitched reed I5 is formed, folded in spaced relation over a lower portion I8, in which the high pitched reed I6 is formed. This arrangement is such that the reed construction, when outside the neck section I3, is too large to slide into the neck section but may be' compressed and inserted into the neck section. When permitted to respond to the inherent resilience of the material of which it is fabricated, the reed .construction I4 is self-retaining in the neck section I 3. with each of said reeds directed to its related horn section.

Provided on the outer periphery of the neck section I3 is a plurality of annular ribs 20 which each of said reeds is directed to a related one of said horn sections, each horn section will eifect an amplification of the sound produced by that reed directed thereto.

Cast integral with the horn and adapted to assist in the mounting thereof on a bicycle handle bar or the like is a mounting element 22 (Figs.

' formed mounting element 22.

2 and 3) which element is formed with a standard 23 having reinforcing ribs 24, and forwardly and rearwardly extending arms 25 and 26, respectively, each having a threaded bolt hole 21.

Adapted to cooperate with said integral mounting element 22 is an independently formed mounting element 38 (Figs. 5 and 6), which element is also provided with forwardly and rearwardly extending arms 3| and 32, respectively, having threadless bolt holes 33 therein. It is well known how said integral and independently formed elements, when made to embrace a round or similarly formed structure such as a bicycle handle bar, may be bolted together for eifecting the mounting of said horn I 0.

A second embodiment $5 of the invention is shown in Figs. 7 to 9, which is similar to the first in that it, too, is of a one-piece die cast construction and includes a first horn section II and a second horn sectionlZ, a neck section I3, a plurality of annular ribs 20 formed on the outer periphery of the neck section for facilitating the fastening thereto of a bulb 2i, and an integrally Whereas the inlets into both the horn sections l l and i2 of the first embodiment were of the same restrictive dimenslons, the inlets into the horn sections of the present embodiment are differently restrictive. That is, the inlet 36 to the second horn section i2 in this embodiment is cast smaller than that to the first horn section I I.

Also adapted to be disposed and retained in the neck section iii of th present embodiment is a modified resilient reed construction 31 (Figs. 7, 8 and 9) which includes a single reed 38 formed in a fiat portion 38 thereof, and longitudinally and downwardly extending arcuate side portions GB. To insert this modified reed construction into the neck section 13 the said side portions E8. are pressed together. This makes the widthwise dimension of the reed construction smaller than the internal diameter of the neck section and permits the construction to be inserted thereinto. Once in the neck section the resilience of the reed construction is suificient to retain it therein.

Inasmuch as the just described embodiment includes but a single reed 38, squeezing of the bulb 2! to force air past the reed eifects but a singly pitched sound. lengths of the horn sections II and I2 and the restrictive inlet 36 to the horn section l3 so affect the mentioned singly pitched sound as to provide a dual tone.

In the modification of the invention shown in Fig. 10, there is mounted in each of the horn sections H and i2 closely adjacent the neck section 53 a tubular plug G8. The plugs 40 are preferaoly iormed of cork but may be, formed .of rubber or a synthetic resinous material. Mounted in position through each of the plugs 40, there is a reed member i! The reed members are of different lengths so as to produce a difierent tone when air is forced past the reed members M by squeezing the bulb 2 i.

In other respects the forms of the invention However, the different shown in Figs. 7 to 9 and in Fig. 10 are similar to the form shown in Figs. 1 to 6 and like reference numerals are used to identify like, parts throughout.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new, and. desire to secure by United States Letters Patent is:

1. Thecombination with a reed horn includin a pair of difierently pitched horns, a neck section common to the inlets of said horns, and means for blasting air through said neck section; of a one-piece resilient construction comprising one portion folded over a second portion in spaced relation, a reed formed in said one portion and a differently pitched reed formed in said second portion, said portions be ing compressible together to permit the insertion of the construction in the neck section of said horn, and the resilience of said construction being effective for the retention thereof in said neck section with each of said reeds directed toward a related one of said horn inlets.

2. A reed horn comprising a pair of integral and differently pitched horns, a neck section common to the inlets of both of said horns, means for blasting air through said neck section; a one-piece resilient construction comprising one portion folded over a second portion in spaced relation, a med formed in said one portion and it differently pitched reed formed in said second portion, said portions being compressible together to permit the insertion of the construction in the neck section of said horn, the resilience of said construction being eiiective for the retention thereof in said necksection with each of said reeds directed toward a related one of said horn inlets; a plurality of annular ribs formed on the outer periphery of said neck section to secure the air blasting means thereto; a mounting element formed integral with said horns; and an independent mounting element associated with said integral element.
